Definately not. But it could be the way you promote the casino. If you say “Click here for a 100% $200 Bonus” and in reality it is a “50% $100” bonus then it might be normal as you’re raised the player’s expectations and they feel let down when they get there.
Failing something like that, go through your own link and do a download, see if it registers.

Simmo!
